Hi Maciej, I'm using LDA for delivery email in mailbox (Maildir) and I think(hope) that switching to LMTP via director will fix my problem, but I d'ont know why wiht old kernel works and with recent no. Are you using POP/IMAP and LMTP via director so any update to dovecot indexes is done from the same server?
